Another long letter of the same batch will be found the first placed in the second volume of Castlereagh, though an examination of it shows that it belongs to the middle of the previous volume. Detailed reference is made to Father O'Coigly's mission and movements, both in France and in London. One is struck by the accuracy of its information regarding the Ulster United Irishmen, of whom Turner was one. Of MacMahon, who travelled to Paris with O'Coigly, we learn that, '_tired of politics_, especially those of France, he is to write to Citoyen Jean Thomas,[55] _à la poste restante à Hamburg_, whom he looks on as a good patriot.'[56] It will be remembered that a similar phrase occurs in the letter of Downshire's friend, printed by Froude, _i.e._ Rowan had 'professed himself sick of politics.' Again, 'I found Maitland and Stewart, of Acton, both heartily sick of politics.' How to hang O'Coigly was now the difficulty. The Government knew--from somebody who had worked with him--that he was deep in the treason; but nothing could persuade the informer to prosecute him openly. On April 11, 1798, Wickham writes from Whitehall:-- It is most exceedingly to be lamented that no person can be sent over from Ireland to prove Coigly's handwriting. Proof of that kind would be so extremely material, that I have no doubt that the law officers would think it right to put off the trial if they could have any hope of any person being found, in a short time, who could speak distinctly to his handwriting.[57] The secret adviser who, as Portland said, 'should be detained,' worked his brain until at length a man, hailing from a place suspiciously familiar to Turner, is sent for to swear to the point. Samuel Turner, formerly of Newry, had intimate knowledge of every man in the place. One Frederick Dutton, described as 'of Newry,' was now subpœnaed by the Crown to swear to O'Coigly's handwriting in a letter addressed to Lord Edward Fitzgerald. 'He claimed to have seen Coigly write his name for the purpose of getting a watch raffled which belonged to a poor man under sentence of death.' Dutton had been a dismissed servant and had kept a public-house at Newry without a licence.[58] Turner--it seems absurd to doubt the identity--got back to London on Tuesday, May 15, 1798. What secret help he gave to the law officers can only be inferred, for they pledged themselves that he should never be asked to come forward publicly. Though O'Connor, O'Coigly, and Binns[59] were arrested on March 1, their trials did not take place till late in May 1798. The Duke of Norfolk, Lords Moira, Suffolk, Oxford, John Russell, and Thanet, Fox, Sheridan, Whitbread, Erskine, Grattan, all testified to O'Connor's character. All the prisoners were acquitted, except the priest, notwithstanding that Lord Cloncurry paid a counsel to defend him. He was hanged on Penenden Heath, June 7, 1798. Judge Buller had leant heavily on O'Coigly in his charge.
